Carrier FF1DNA030075AAAA Blower Wheel
The blower wheel has fins all around it and is spun around by a motor to produce an airflow throughout an entire house. It is occasionally called a squirrel cage because of its remarkable resemblance of a very large wheel a hamster would run on. Whatever you want to call it, it is a necessary piece of equipment of any HVAC system that needs proper air pressure within the ductwork.
What to see if the main blower wheel is almost dead?
- If a part of the cage has broken off and it wobbles when spinning
- You detect less than usual air coming out of the vents
- A vibration is heard while the system ramps up
